Stephen J. Sullivan represents clients in all aspects of natural resources with a primary focus on oil and gas exploration and development in the Rocky Mountain area. A large part of his oil and gas practice involves acquisitions and divestitures as well as operational matters. Mr. Sullivan represents mining companies from the initial staking of claims through financing, permitting, and start-up of mining operations. He also represents parties in the purchase of ranches and in the acquisition and sale of water rights in Colorado, including acquisition of water rights and construction of water delivery systems.
Real estate transactions in which Mr. Sullivan has been involved – in both negotiation and legal representation – include land exchanges, open space dedication, mineral development agreements and intergovernmental agreements for construction of transportation and water infrastructure, and development of commercial properties.
Oil and Gas:
- Simultaneous purchase from multiple parties and sale of approximately 100 wells and 23,000 acres of producing and undeveloped coal bed methane properties in the San Juan Basin.

Steve Sullivan's experience in natural resources and the Rocky Mountain west began long before he began his legal career. His experiences on ranches in Wyoming and Nevada provide perspective when addressing land transactions and negotiations between mineral and surface owners. During the energy boom and bust of the 1970s his education included research on the supply of ground water for coal pipeline slurries, engineering of solar and geothermal homes in the Northern Rockies, uranium resource economics and supply, and geologic field work in five western states. He firmly believes that knowledge of the land and the people that live on the land are crucial to providing top notch legal representation and obtaining lasting solutions for his clients.
Mr. Sullivan's passion for the outdoors was fed by wilderness climbing trips, work on his grandfather's ranch, and long days in the prairies and foothills where he learned firsthand how wildlife adapts to changes caused by human development. Technical experience gained from work such as his study while at Princeton University of radioactive leakage into groundwater systems, work for the National Academy of Science on mined land reclamation in Wyoming's Powder River Basin, and modeling of resource availability for the federal government's energy supply models while working in Palo Alto, California provide him with insight on the complexities of issues related to natural resources from the perspective of scientist, developer, land owner and government regulator. This knowledge and experience allows him to focus immediately on key issues and provide timely advice.
His community involvement in Volunteers for Outdoor Colorado, Denver Earth Resources Library, and as a soccer coach evolved into ten years of service as trustee and mayor for the Town of Foxfield and member of the executive council of the Metro Mayors Caucus. Since 1995, Mr. Sullivan has also served on the board of the Colorado Oil and Gas Association. He particularly enjoys taking a "hands-on" approach, whether in negotiations or through direct personal interaction with the people affected. "I'm continually amazed by the intelligence, commitment, and passion of people I represent, and their ability to think outside the box and work toward results which are in the best interests of everyone concerned."
